OBJECTIVE To evaluate the validity and reliability of the Brazilian Portuguese version of the Western Ontario Rotator Cuff Index (WORC). DESIGN AND SETTING A cross-sectional survey at the Physiotherapy Unit and Outpatient Orthopedic and Traumatology Clinic, Universidade Federal de São Paulo. METHODS To test validity, 100 patients with rotator cuff(More)
The aim of this study is to analyze the effects of low-level laser therapy (LLLT) on the regeneration of the sciatic nerve in rats following a complete nerve resection. Male Wistar rats were divided into a control injury group, injury groups irradiated with a 660-nm laser at 10 or 50 J/cm2, and injury groups irradiated with an 808-nm laser at 10 or 50(More)
BACKGROUND Shoulder pain is a very common symptom. Disorders of the rotator cuff tendons due to wear or tear are among the most common causes of shoulder pain and disability. Magnetic resonance imaging (MRI), magnetic resonance arthrography (MRA) and ultrasound (US) are increasingly being used to assess the presence and size of rotator cuff tears to assist(More)
BACKGROUND Clavicle (collarbone) fractures account for around 4% of all fractures; treatment of these fractures is usually non-surgical (conservative). Commonly used treatments are arm slings, strapping, figure-of-eight bandages and splints.This is an update of a Cochrane review first published in 2009. OBJECTIVES To evaluate the effects of different(More)
BACKGROUND Platelet-rich therapies are being used increasingly in the treatment of musculoskeletal soft tissue injuries such as ligament, muscle and tendon tears and tendinopathies. These therapies can be used as the principal treatment or as an augmentation procedure (application after surgical repair or reconstruction). Platelet-rich therapies are(More)
BACKGROUND Dislocation of the acromioclavicular joint is one of the most common shoulder problems in general orthopaedic practice. The question of whether surgery should be used remains controversial. OBJECTIVES To assess the relative effects of surgical versus conservative (non-surgical) interventions for treating acromioclavicular dislocations in(More)
The objective of this study was to provide an assessment of published studies on the wrist arthroscopy. The search was performed from the "Web of Science (WoS) Science Citation Expanded Database" with studies published between January 1, 1990 and March 31, 2011. For research we used the following terms: "Wrist arthroscopy" and "Arthroscopy of the wrist". We(More)
BACKGROUND At present, there is no conclusive evidence regarding the best treatment method for reducible unstable fractures of the distal radius. This study compared the effectiveness of two methods used in surgical treatment of such fractures: percutaneous pinning and external fixation. METHODS We randomly allocated 100 patients into two groups treated(More)
PURPOSE The exact distances from the cutaneous dorsal branches of the digital artery to the proximal interphalangeal joint have been established in a previous anatomic study. The aim of this report is to incorporate these anatomic data into the current way of designing the homodigital adipofascial turn-over flap for cutaneous coverage of the dorsum of the(More)
The authors describe arthroscopic reduction and percutaneous fixation of greater tuberosity fractures of the humerus with displacement of more than 0.5 cm. Arthroscopy for reduction and fixation of this fracture presents the same difficulties and advantages as arthroscopic repair of rotator cuff tears.
